The Intel RST RAID (aka Intel Matrix RAID) is also known as a
fakeraid.  It isn't a hardware RAID, but instead a software RAID that
has a fancy BIOS interface.  I believe that the mdadm tool can examine
the RAID settings, and you can look at /proc/mdstat to see its status,
although from what I remember from previous posts, it's better to just
let the BIOS think it's a JBOD and use the linux software RAID tools
